receiveBufferSizeSocket

Specifies the value in bytes for the lower level datagram buffers. This is the size of the DatagramSocket receive buffer (SO_RCVBUF) on any inbound User Datagram Protocol (UDP) channel.

Use this property to buffer multiple packets in the DatagramSocket layer. If the value of the property is too small, then packets might be lost if the server is overloaded. If the value is too large, then the packets might be delayed.

Data type	String
Default	1024000

sendBufferSizeSocket

Specifies the value, in bytes, for the lower-level datagram buffers, which is the size of the DatagramSocket send buffer (SO_SNDBUF) on any inbound UDP channel.

Use this property to buffer multiple packets in the DatagramSocket layer. If the value of the property is too small, then packets might be lost if the server is overloaded. If the value is too large, then the packets might be delayed.

Data type	String
Default	1024000
